［摘要］成都綠地航校項(xiàng)目由兩棟117m高、相距23m的超高層住宅，及頂部17m高的天際連體別墅組成，其功能組合在國內(nèi)是首次出現(xiàn)。該建筑外形“頭重腳輕”，建筑平面呈L形，剪力墻厚度僅200mm，且別墅層和住宅層豎向構(gòu)件完全不對應(yīng)，采用通常結(jié)構(gòu)體系很難實(shí)現(xiàn)。設(shè)計(jì)中創(chuàng)新性地采用了“半剛性”連體方案，利用住宅屋面與天際別墅之間的架空區(qū)域，設(shè)置了12個(gè)鋼支撐筒來承托上部轉(zhuǎn)換桁架，并利用鋼支撐筒的變形能力來協(xié)調(diào)兩棟塔樓的相對變形。計(jì)算結(jié)果表明，“半剛性”連體方案的位移和剛度與沒有天際別墅的單棟住宅塔樓非常接近，避免了因傳統(tǒng)剛性連體結(jié)構(gòu)剛度和地震力急劇增大而導(dǎo)致塔樓200mm厚剪力墻破壞的問題。該方案不僅解決了建筑和結(jié)構(gòu)的諸多矛盾，還具有很好的經(jīng)濟(jì)效益。

Abstract:Chengdu Greenland Hangxiao Project is composed of two super high-rise residences with a height of 117m and a distance of 23m, and a 17m high skyline connected villa on the top of the building. The combination of residential tower plus connected villa is first used in China. The building has a top-heavy appearance, the building plane is L-shaped, the thickness of shear wall is only 200mm, and the vertical components of villa floor and residential floor are totally different, so it is difficult to achieve by using the usual structural system. An innovative semi-rigid connected system was used in the design. Using the overhead area between the residential roof and the skyline villa, 12 steel supporting tubes were set to support the upper transfer truss, and the deformation capacity of the steel tubes was used to coordinate the relative deformation of the two tower buildings. The analysis results show that the displacement and rigidity of the semi-rigid connected plan are very close to that of a single residential tower without a skyline villa. The new system avoids the problem of the traditional rigid connected system, including the rapid increase of stiffness and seismic force, and the easy failure of 200mm thick shear wall of the tower. This system not only solves many contradictions between architecture and structure, but also has good economic benefits.
Keywords:Chengdu Greenland Hangxiao; semi-rigid connection; steel support tube; high-position isolation
